Description

The WPUpper Share Buttons plugin for WordPress is vulnerable to Authenticated (Admin+) Stored Cross-Site Scripting via the plugin's settings in versions up to, and including, 3.42 due to insufficient input sanitization and output escaping. This makes it possible for adminitrator-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
